STEAM-HEATED SAD-IRON.

Patented May 12, 1.91.4.

To all whom it may concern:

Be it known that I, Vieron PIETRAFESA, of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvements in SteameI-Ieated Sad-Irons, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to certain improvements in steam heated sad irons adapted to be used more particularly in clothing manufactories for pressing cloth and newly made garments.

An object is to provide a self-cleaning steam heated sad iron so as to make it practically impossible to injure the cloth or garment by either heating or burning even in the hands of the most unskilled operators.

Another object is to provide the sad irons with interior means for distributing the steam uniformly at the sides and across the major portion of the bottom and also to provide the chambers or compartments with re versely inclined bottoms leading respectively from the steam inlet to the drainage outlet so as to avoid as far as possible accumula tions of water of condensation in either of the chambers.

A further object is to provide the steam inlet and drainage outlet pipes with suitable valves in close proximity to the sad iron for controlling the inflow of steam and exit of the water of condensation since it may be desirable when the iron is at rest for a short period of time to retain a body of water therein for the purpose of keepin@ the iron warm, the degree of temperature eing regulated by the degree of opening of the steam supply valve or the degree of opening of the drainage outlet.

Other objects and uses will be brought out in the following description.

In the drawings Figure 1 is a top plan of the sad iron embodying the various features of my invention. Figs. 2 and 3 are sectional views of the same sad iron taken respectively on lines 2 2, and 3 3, Fig. 1. Figs. 4 and 5 are horizontal sectional views through the same sad iron in the planes respectively of the steam inlet and drainage outlet. Fig. 6 is a longitudinal vertical sectional view of the iron through one of the drainage outlet channels to show the inclined bottom wall thereof taken on line (5 6, Fig. 1, omitting the handle, feed and delivery pipes.

As illustrated, this sad iron comprises an elongated body 1 of cast iron or similar material having the front ends of its sides converging to a point and its lower and upper 'faces substantially parallel, the lower face being polished in the usual manner for this class of iron. The major portions ot the sides at the rear of the point are also parallel while the end opposite the point is disposed at substantially right angles to the sides and is provided with a steam inlet port Q and a drainage port 3 between the sides in a plane one above the other, the inlet port being connected to a steam supply pipe 4 while the drainage outlet port is connected to a similar pipe 5. These pipes are provided with suitable valves G- and 7 having operating handles 8 by which either valve may be opened or closed independently ot' the other to regulate the admission of steam or outlet ot' water ot condensation from the interior of the iron, thereby permitting the operator to regulate the temperature. These valves are preferably located in close proximity to the heel of the iron for convenient operation, the portions of the pipes just beyond the valves being connected to flexible hose Q united close to each other by a sleeve 10 of any suitable material which will hold the adjacent ends of the hose in connection with the valve nipples and at the same time avoid sharp bends of the hose at the connections, thereby increasing the life of the hose and avoiding troublesome leakages.

The interior chamber ol the iron is nearly eoextensive in length and width with the iron but is divided by vertical partitions 11 into a central compartment 1Q- and opposite outer compartments 13 the partitions being united to the end as liland also to the bottom and top of the iron and preferably extend lengthwise of said iron at opposite sides oit' the ports Q and 3 parallel with each other and with the sides of the iron. These partitions 11 are nearly coextensive in .length with the length ot' the interior chamber but terminate a short distance from the front end thereof so as to establish communication between the front ends of the compartments 1Q-- and 13 as the only means of communication between said compartments, thereby causing the steam to travel nearly the whole length of the iron before returning rearwardly into the outer compartments 13-.

It will be observed that the partitions w11- and outer walls of the iron are come paratively thin although the sides are somewhat thicker than the partition while the bottom and ends are still thicker than the sides so as to retain the heat for a greater period of time and afford the necessary weight for most efficient ironing or pressing. The object, therefore, of these partitions is to split up the iron into relatively thin walls for more even distribution of the steam and greater rapidity of heating.

Another feature of novelty of this iron consists in inclining the bottom of the chamber 12- from the steam inlet port m2- to its point of mergence .with the chambers -l8 at the front end of the iron while the bottoms of the chambers l3- are `inclined from the front end or point of mergence of such chambers toward the rear end or heel of the iron for communication with the drainage outlet -3-, thereby eX- pediting the drainage of any water of condensation which may tend to accumulate in the iron and permitting the use of live steam under its full heat eiiiciency when desired. That is, any water of condensation which may accumulate in the chamber 12- gravitates'quiclly into the front ends of the chambers M13- and thenc-e rearwardly along the inclined bottoms of the latter chambers into the drainage pipe -5- which may be connected to any soil pipe or other place of deposit of such water. On the other hand, if it is desired to lower the temperature of the iron, as may be necessary in some classes of work, the drainage valve 7- may be wholly closed or partially closed to retain the water of condensation and thereby lower the temperature of the iron or, at the saine time, the steam valve -G- may be also partially closed so as to reduce the amount of steam entering the chamber. lf the highest degree of heating efficiency is desired, both valves may be fully opened to allow the live steam to circulate through the iron.

rlhis iron may be provided with any suitable handle, as -15-, preferably of wood or equivalent heat-insulating material supported in suitable standards 16- some distance from the iron so as to be conveniently handled without inconvenience to the operator, the standards being secured to the top of the iron by any suitable fastening means as bolts or screws -17-.

The operation of my invention will now be readily understood upon reference to the foregoing description and the accompanying drawings and it is evident that some changes may be made in the detail of construction and arrangement of the various parts thereof without departing from the spirit of my invention, and, therefore, I do not limit myself to the precise structure shown and described.

li/Vhat l claim is: p

l. A hollow sad iron having parallel partitions extending forwardly from its rear end and integrally united to the top and bottom of the iron to form an intervening chamber, said partitions being spaced apart from the sides of the iron to form additional chambers communicating with the intermediate chamber at the front end of the iron, the rear end of the chamber being provided with a steam pipe communicating with the adjacent end of the intermediate chamber, the lbottom of .the intermediate chamber being inclined downwardly and forwardly Vwhile the bottoms of the outer chambers are inclined downwardly and rearwardly, said rear end of the iron being also provided with a drainage outlet communieating with the adjacent ends of the outer chambers.

2. A hollow sad iron having lengthwise partitions extending forwardly from its rear end and spaced apart from each other and from the opposite sides of the iron to form intervening chambers, said chambers communicating with each other at the front end of the iron, the rear ends of the outer cham bers communicating with each other at the rear of and around the partitions, the rear end of the iron being provided with a steam inlet pipe communicating with the intermediate chamber, and a drainage pipe coinmunicating with the connection between the rear ends of the outer chambers, the bottom of the intermediate chamber being inclined downwardly and forwardly while the bottoms of the outer chambers incline downwardly and rearwardly.

1n witness Vwhereof 1 have hereunto set my hand this 28th day of July, 1913.
